And I expected this to happen:

can switch composer 1.* to composer 2.*

[johnstevenson]

This is very weird. I can confirm that updating from 1.10.24 to 2.2.3 doesn't work on PHP-8.1, but I have no idea why (PHP-8.0 works fine).

Also, updating and rolling back 2.2 versions in PHP-8.1 is not a problem.

[Seldaek]

Thanks for pinpointing the problem and reporting it upstream @johnstevenson - leaving this open for now until the bug is fixed in PHP. For the time being please try to self-update using a version lower than 8.1 @miaotiao or simply reinstall Composer from scratch so you get the latest.

[johnstevenson]

@miaotiao You can also rename the file yourself. Since you were running as an Admin, the file was downloaded as C:\ProgramData\ComposerSetup\bin\composer-temp.phar so just rename it manually to composer.phar. (It didn't get deleted as it should have).

@Seldaek Fix on the way for 1.10 versions.

[Seldaek]

Not sure it's worth fixing on our end if a 8.1.x fix is also coming.

[johnstevenson]

Ah, I've already done it. Anyway, it is up to you (it would at least allow 8.1.0 and 8.1.1 versions to keep working).

[miaotiao]

Thank you so much , happy weekend

[Seldaek]

1.10.25 released with the fix, but to self-update to it you'll have to use php<8.1 of course :)
